DETAILED DESCRIPTION
[0019] Please refer to FIG. 1. FIG. 1 is a functional block diagram
of a protocol system 10 according to an embodiment of the present
invention. The protocol system 10 includes at least one signal
receiving device 12 and a signal outputting device 14. The signal
outputting device 14 can automatically transmit a datum to the
signal receiving device 12 via wireless transmission, and the
signal receiving device 12 can execute corresponding application
program according to the updated datum. The signal receiving device
12 includes an actuating unit 16 and a first wireless transmission
unit 18. The signal outputting device 14 includes a second wireless
transmission unit 20, a detecting unit 22 and a processing unit 24.
The detecting unit 22 can output a detecting signal S1 for
detecting whether the signal receiving device 12 is located within
an effective range of the detecting signal S1. The actuating unit
16 can generate a reacting signal S2 according to the detecting
signal S1, and the reacting signal S2 is received by the detecting
unit 22.
[0020] As shown in FIG. 1, the processing unit 24 is electrically
connected to the second wireless transmission unit 20 and the
detecting unit 22. When the detecting unit 22 receives the reacting
signal S2 outputted from the signal receiving device 12, the
detecting unit 22 can analyze an intensity of the reacting signal
S2 to acquire a distance between the signal receiving device 12 and
the signal outputting device 14 because a value of the intensity of
the reacting signal S2 is inversely proportional to the distance.
As the distance is smaller than a predetermined threshold, the
processing unit 24 transmits the datum from the second wireless
transmission unit 20 to the first wireless transmission unit 18, or
the datum is transmitted with the detecting signal S1 to the signal
receiving device 12 via the wireless transmission. The datum can be
firmware updating information of the signal receiving device 12, or
control parameter stored inside the signal outputting device 14 for
operating the signal receiving device 12. The signal receiving
device 12 can execute the corresponding application program
according to the datum from the signal outputting device 14.
Applications of the signal receiving device 12 and the signal
outputting device 14 are introduced as following.
[0021] Near field communication (NFC) function of the protocol
system 10 is applied to the wireless transmission. The actuating
unit 16 can be a conductive wire, a reflective component with
reflective property, or an electric wave follower. For example, the
actuating unit 16 is the reflective component, and the detecting
unit 22 outputs the optical detecting signal S1. The actuating unit
166 can reflect the optical detecting signal S1 to generate the
reacting signal S2, and the reacting signal S2 is received by the
detecting unit 22. A reflecting energy intensity of the reacting
signal S2 becomes stronger as the signal outputting device 14
approaches to the signal receiving device 12. The processing unit
24 can analyze the reacting signal S2 to acquire a value of the
distance, so as to determine whether connection between the first
wireless transmission unit 18 and the second wireless transmission
unit 20 is automatically established.
[0022] The actuating unit 16 and the detecting unit 22 can further
be the conductive wires, which have own electromagnetic fields.
When the distance between the signal outputting device 14 and the
signal receiving device 12 is smaller than the threshold, the
electromagnetic field are coupled due to the adjacent conductive
wires for varying electromagnetic flux of the reacting signal S2,
and the processing unit 24 can select the nearest signal receiving
device 12 relative to the signal outputting device 14 for
outputting a request of switching connection. Besides, the
actuating unit 16 can further be the electric wave follower, and
the detecting unit 22 can be a radiofrequency identification label,
which transmits the signal via the electromagnetic field with radio
frequency. When the electric wave follower is within the effective
range of the radiofrequency identification label, the electric wave
follower can transmit energy to the radiofrequency identification
label via the reacting signal S2, so as to drive the radiofrequency
identification label to output a control command for establishing
the connection. Further, the radiofrequency identification label
can have own power source, and the radiofrequency identification
label can actively output the control command.
[0023] The protocol system 10 can further include a plurality of
signal receiving devices 12. When the detecting unit 22 detects a
plurality of reacting signals S2, the processing unit 24 can
respectively acquire distances between the signal outputting device
14 and the signal receiving devices 12 corresponding to each
reacting signal S2 according to values of the reacting signals S2.
Then, the processing unit 24 can select the signal receiving device
12 that the distance is smaller than the threshold to execute the
datum transmission, so that the signal outputting device 14 of the
present invention can synchronously transmit the datum to the
signal receiving devices 12 that are located within the effective
detecting range. It is to say, the user can utilize one signal
outputting device 14 to simultaneously control the plurality of
signal receiving devices 12, so as to increase convenience of datum
updating.
[0024] Please refer to FIG. 2 and FIG. 3. FIG. 2 is a flow chart of
updating the datum by the signal outputting device 14 according to
the embodiment of the present invention. FIG. 3 is a flow chart of
updating the datum by the signal receiving device 12 according to
the embodiment of the present invention. Methods of FIG. 2 and FIG.
3 can be applied to the protocol system 10 shown in FIG. 1. First,
step 200 is executed to utilize the detecting unit 22 to output the
detecting signal S1 for searching whether the signal receiving
device 12 is located within the effective range of the detecting
signal S1. Steps 202 and 204 are executed that the detecting unit
22 receives the reacting signal S2 from the signal receiving device
12 when detecting the signal receiving device 12, and then the
processing unit 24 analyzes the reacting signal S2. Because the
value of the reacting signal S2 represents the distance between the
signal outputting device 14 and the signal receiving device 12,
step 206 is executed to acquire the distance and to compare the
distance with the threshold by the processing unit 24.
[0025] As the distance is greater than the threshold, there is no
signal receiving device 12 located within the effective detecting
range. Step 200 is executed that the signal outputting device 14
continuously outputs the detecting signal S1 via the detecting unit
22 for detecting whether the matched signal receiving device 12
exists. As the distance is smaller than the threshold, steps 208
and 210 are executed, so the processing unit 24 outputs the request
of the datum transmission to the signal receiving device 12, and
transmits the datum to the signal receiving device 12 via the
second wireless unit 20 and first wireless transmission unit 18
after the request is allowed. In the present invention, one signal
outputting device 14 can be simultaneously matched with the
plurality of signal receiving devices 12. When the detecting unit
22 of the signal outputting device 14 receives the plurality of
reacting signals S2, the processing unit 24 can select the signal
receiving devices 12 that the distances are smaller than the
threshold according to the values of the reacting signals S2, so as
to output the request of the datum transmission and to transmit the
datum in accordance with the selected signal receiving devices
12.
[0026] Accordingly, the signal receiving device 12 executes steps
300 and 302, the actuating unit 16 receives the detecting signal
S1, and generates the reacting signal S2 according to the detecting
signal S1. As the signal receiving device 12 is located within the
effective detecting range of the signal outputting device 14, the
signal receiving device 12 can receive the request of the datum
transmission from the signal outputting device 14. Then, step 304
is executed to accept the request of the datum transmission, and
the signal receiving device 12 can receive the datum outputted from
the signal outputting device 14. Therefore, the signal receiving
device 12 of the present invention can conveniently and rapidly
download the datum for executing the application program. The
signal receiving device 12 can immediately update the control
parameter or the firmware information when the signal receiving
device 12 is communicated with the signal outputting device 14 via
the wireless connection, so as to overcome the updating
inconvenient drawback of wire transmission and manual verification
in the prior art.
[0027] The signal receiving device 12 and the signal outputting
device 14 can be the wireless mice. Please refer to FIG. 4. FIG. 4
is a diagram of the protocol system 10 applied to the wireless
mouse according to the embodiment of the present invention. When
the user has the private signal outputting device 14, a plurality
of personal control parameters, such as illumination adjustment of
light emitting diode, scintillating frequency of the light emitting
diode, click definition of the button, macro definition of the
button, or definition of button assembly, can be set on the signal
outputting device 14 according to user's custom. The personal
control parameters can be stored inside a first memory unit 26 of
the signal outputting device 14, as shown in FIG. 1.
[0028] As the original one is replaced by a new wireless mouse (the
signal receiving device 12) or a plurality of private wireless mice
(the signal receiving device 12) is intend to be disposed on
different computer hosts, the NFC function of the original wireless
mouse (the signal outputting device 14) can be actuated, the other
wireless mice (the signal receiving device 12) are moved into the
effective detecting range of the original wireless mouse (the
signal outputting device 14), so that the plurality of wireless
mice (the signal receiving device 12 and the signal outputting
device 14) can respectively keep the connection with the
corresponding wireless transceivers (the dongle), and one of the
wireless mice (the signal outputting device 14) can rapidly copy
and transmit the control parameter or the firmware updating
information to the other wireless mice (the signal receiving device
12). The control parameter or the firmware updating information can
be stored inside a second memory unit 28 of the signal receiving
device 12, as shown in FIG. 1. Therefore, the wireless mouse
applied to the NFC function of the present invention has preferable
convenience for updating the datum.
[0029] In addition, the signal outputting device 14 can further be
the portable electronic device, such as a handheld phone. The
signal receiving device 12 can be set as the electric equipment
product, such as acoustic equipment, a lamp, an air conditioner, a
television and so on. The electric equipment products are driven by
a central controller (the signal receiving device 12). Please refer
to FIG. 5. FIG. 5 is a diagram of the protocol system 10 applied to
the electric equipment product according to the embodiment of the
present invention. In this embodiment, the user can input the
environmental control parameter, such as selection of song/channel,
sound volume, brightness, adjustment of temperature/humidity, into
the signal outputting device 14. As the portable electronic device
(the signal outputting device 14) is put adjacent to the central
controller (the signal receiving device 12), the central controller
can automatically receive the above-mentioned environmental control
parameters, so as to immediately drive each electric equipment
product to execute the corresponding operation. Thus, the user can
utilize the present invention to rapidly adjust the environmental
situation when entering a specific environment, such as staying
indoors or sitting in the car.
[0030] Please refer to FIG. 6. FIG. 6 is a diagram of the protocol
system 10 applied to the electric equipment product according to
the other embodiment of the present invention. The user certainly
can move the portable electronic device (the signal outputting
device 14) respectively close to each electric equipment product
(the signal receiving device 12) for inputting the predetermined
individually environmental control parameter. Further, when the
portable electronic device (the signal outputting device 14) moves
close to the electric equipment product (the signal receiving
device 12), the electric equipment product not only accepts the
request of the datum transmission (the control parameter), but also
can simultaneously output a request of updating the firmware
information; meanwhile, the portable electronic device can download
the firmware updating information in an externally transmitting
manner, such as the optical disk drive, the flash disk or Internet
communication. Then, the firmware updating information stored
inside the first memory unit 26 can transfer to the second memory
unit 28 of the electric equipment product, so as to keep hardware
of the electric equipment product at best mode. Thus, the smart
electric equipment product can utilize the protocol system 10 of
the present invention to immediately update the firmware
information for increasing the preferably operational efficiency of
the product.
[0031] In the other embodiment, the portable electronic device (the
signal outputting device 14) can further be applied to an entrance
management system. Please refer to FIG. 7. FIG. 7 is a diagram of
the protocol system 10 applied to the entrance management according
to the embodiment of the present invention. The user can move the
portable electronic device (the signal outputting device 14) close
to a host (the signal receiving device 12) of the entrance manager
for downloading the decoding information. As walking through the
door with an electronic lock, the user can put the portable
electronic device over the electronic lock (the signal receiving
device 12) to transmit the decoding information, and the electronic
lock can verify the decoding information to lock or unlock the
door. Because the conventional magnetic paper card is easy to lose
and damage, the conventional magnetic paper card with throw-away
type can be replaced by the protocol system 10 and the related
method of automatically updating the datum of the present
invention, to provide the convenient solution according to user's
custom.
[0032] In conclusion, the protocol system of the present invention
utilizes the NFC function to immediately transmit the control
parameter, the firmware updating information and the decoding
information from the signal outputting device to the signal
receiving device located within the effective detecting range via
the wireless transmission, so as to replace the conventional cable
transmission method. The signal receiving device and the signal
outputting device of the protocol system of the present invention
does not shut down the operating system for programming the updated
datum. On the contrary, the protocol system of the present
invention can simultaneously upload and download the updated datum
when the operating system is executed. Comparing to the prior art,
the present invention can detect the relative distance to
immediately update the datum for easy operation, so as to simplify
procedures of updating the datum, instead of the conventional cable
transmission method, for increasing operational convenience and
market competition of the product.
[0033] Those skilled in the art will readily observe that numerous
modifications and alterations of the device and method may be made
while retaining the teachings of the invention. Accordingly, the
above disclosure should be construed as limited only by the metes
and bounds of the appended claims.
